All paths from any LOAD’s egress P-TCB to any LOAD’s ingress P-TCB must traverse
sequences that are identical in time and components as they pass through the TSE core. Where
the common core path extends out to the Load devices, this rule includes paths from any LOAD A
to any LOAD B, the reverse paths from B to A, and any self-loops from A to A or B to B. As
mentioned below, some Loads may be further from the core, their paths being extended by the use
of extra TSE devices which serve as gather/scatter devices for low aggregate bandwidth Loads.
These extended path portions need not be identical to other paths, but they must be traversed
before and after the common core paths.
Time delays on all longest simplex paths must begin with zero at the source LOAD (The longest
paths are those paths that are extended, if any. Normally, all paths are “l(fā)ongest” and all begin at
time zero.). The time delays on all paths must be strictly increasing, and the delays on all path
delays must be identical when they reach the TSE core column.
12.13.4 Examples of Legal Composition
The following figures give examples of legal fabric compositions. Appropriate time delays are
indicated by monotonically increasing integers.
